Ok seriously guys, sonic in galaxy 2? It's just a gigantic impossibility for so many reasons, mostly gameplay construction, they'd have to make an entirely new set of levels for sonic. They'd never do it.... ever. Ever. We were lucky enough to get luigi in galaxy to begin with. They don't throw enough of a bone to their own characters to ever give two sh'ts about sega's, and then actually put him in a real mario game. Maybe I've been duped and this was always a joke, but Sonic Team killed sonic forever. Deadsies.
Optimistically, Nintendo will address one of their major franchises that hasn't seen a Wii iteration yet. Probably, they'll give harder release dates for Galaxy and Metroid, and lets you know that Zelda has a release date of neverE10^9. (Yes, Giganever). Impossibly, Nintendo ever does anything more with sonic than throw him on a track to perpetuate the ridiculous notion that he could be beaten by slow-ass, fat-ass, plumber-cracked mario.
